Here again is that Zilla 40 Critter Cage; just the other day, I ordered two of these for around $90 from a local pet supply store - it was close, these or those really nice Show Case Cages I mentioned earlier in this thread; but the lack of side viewing followed by cost is what made me finall choose the 40 Critter Cage. I too thought of getting a larger 125 or 150 tank and putting a divider in it to keep our two corns seperate, but both at the same eye level, but doing some measurements in our living room and TV room, would really limit where this size of tank could go; so went with 2 Zilla 40s and picked up a stand that keeps on on top of the other and allows for near full viewing on all sides. Once I get them and get our snakes into their new homes, I'll post some pics.
Good luck with your search...
